No power to fuel relay

[Tony V.]

I have no power to my fuel relay on the pump side. Where does the power to the pump come from? The relay was tested and works. The pump is new and works. Does anyone have a wiring diagram?

Start with the fuse...

I have a 2001 that cranks with no start. So far I've:

• Pulled a coil and used a new spark plug touching the block and got spark
• Used scan tool to see the immobilizer signal turn on/off with key
• Tested the pump relay
• Checked voltage at relay pump power while turning key to start, shows 10v steadily dropping to 4v over 5 seconds
• Checked voltage at fuse (fuse is good) and get similar voltage
• Disconnected crank sensor and got P code for sensor and saw rpm not moving, reconnected and no code/rpm bounce to 300

Next step to pull battery and use test leads to power pump at connector?

Is the voltage I'm getting at the relay/fuse correct? I've heard the pump only gets power for a second when cranking then only gets more power when the engine fires?

How do I get the fuel out if the pump is actually dead?

 

Thanks in advance,
